Driving in Windy Conditions

I was driving on I-80 through the Utah salt plains almost to the Nevada boarder heading west a few years ago. It was in September so it was a summer storm that consisted of high winds and rain. My clue should have been the rain was going sideways instead of down. I slowed but kept driving because I need to get back home. I decided to quit driving when the wind actually pushed me sideways into the next lane. The steering wheel was turned to the right, but I was going left. I had to slow to under 20 to regain control. Luckily there was zero traffic around me. I drove at under 20 mph to the next off ramp and found a place to turn the RV into the wind and just waited until the storm passed.
